以FPGA为数字逻辑平台,借助继电器矩阵和多路模拟开关,以ADS1211为核心,在单片机控制下,联合实现手持式虚拟/智能存储示波表中数字多用表功能,实验表明该设计是行之有效的。文中介绍了数字多用表的系统结构,重点讨论了其测量电路和智能控制方案。
Abstract:
The digital multimeter in virtual/intellect digital-oscillorgaph was fulfilled, which was controlled by singlechip computer by relay matrix and analogue switches,in which FPGA was used for digital logical plot-form, ADS1211 for kernel chip, the experiment showed the design was feasible, the system struction was present-ed in the paper, measure circuit and intellect control plan of digital multimeter were mainly given.
